使用Spring Boot構建Spring MVC應用程序

我試圖使用Spring Boot構建一個非常簡單的Spring MVC應用程序。現在我所有的嘗試都失敗了。這裏是CONFIGRATION：使用Spring Boot構建Spring MVC應用程序

WebConfig：

@SpringBootApplication 
@ComponentScan("newTestProject") 
public class WebConfig extends WebMvcConfigurerAdapter { 

    public static void main(String[] args) throws Exception { 
     SpringApplication.run(WebConfig.class, args); 
    } 

    @Bean 
    public ViewResolver jspViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/WEB-INF/views/"); 
     resolver.setSuffix(".jsp"); 
     resolver.setExposeContextBeansAsAttributes(true); 
     return resolver; 
    } 
}

WebAppInitializer：

@Configuration 
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected String[] getServletMappings() { 
     return new String[]{"/"}; 
    } 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class<?>[]{}; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class<?>[]{WebConfig.class}; 
    } 
}

控制器：

@Controller 
public class IndexController { 

    @RequestMapping(value = "/") 
    public String index() { 
     return "index"; 
    } 
}

POM：

有在控制檯中沒有錯誤消息：

結果應該在我的瀏覽器中顯示的index.jsp，而是我得到的白色標籤錯誤頁面。這個配置有什麼問題？

是否有一個原因，你（1）使用戰爭的包裝和（2）手動指定'@ ComponentScan'範圍是什麼？ – chrylis

戰爭/罐子 - 它沒有區別。兩種情況下的結果都是一樣的。有或沒有@ComponentScan的結果也是一樣的。白標籤錯誤頁面。 – sva605

使用罐子。什麼是文件夾配置？啓動日誌是什麼樣的？什麼是類的包？ –

1）刪除WebAppInitializer類 - 它不是必需的，因爲spring boot會自動配置它。

2）刪除web.xml。我不知道你在那裏有什麼，但是因爲你使用了註解配置，所以它不是必需的。

3）通過在WebConfig中覆蓋configureDefaultServletHandling來啓用默認的servlet。

@Override 
public void configureDefaultServletHandling(
     DefaultServletHandlerConfigurer configurer) { 
    configurer.enable(); 
}

4）添加以下Maven的依賴關係：

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-tomcat</artifactId> 
    <scope>provided</scope> 
</dependency> 
<dependency> 
    <groupId>org.apache.tomcat.embed</groupId> 
    <artifactId>tomcat-embed-jasper</artifactId> 
    <scope>provided</scope> 
</dependency>

5）使用maven

$ mvn clean spring-boot:run

PS運行項目：我不知道你有你jsp文件。但是，如果您使用純html，這種方法肯定會有效。如果你使用的是jstl東西，有你有添加JSTL的依賴以及

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>jstl</artifactId> 
</dependency>
